ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question
While planning the audit subsystem for a new payment-processing microservice, the security architect must ensure investigators can later reconstruct a precise sequence of user actions for accountability purposes. Which control MOST directly supports this requirement?
Synchronize every host and container to a trusted time source and timestamp each log entry.
Anonymize user identifiers in logs before forwarding them to the SIEM.
Compress and archive all logs to offline storage after 24 hours.
Purge high-volume debug logs daily to conserve local disk space.
Accurate, synchronized timestamps let investigators place events from different components on a single, trusted timeline. NIST SP 800-92 notes that without trustworthy time information, log analysis cannot determine the order or relationship of actions-undermining accountability. Compressing or deleting logs affects retention, not chronology. Masking user IDs removes attribution data and actually hinders investigations.
